Search Lost IS (Rank) Explained
As a search marketer, you have more than likely come across a metric in Google Ads called search lost IS (rank). This is the search impression share lost due to Ad Rank, or the percentage of time your ad was not shown to Google searches that matched your keywords. You may wonder, “How is this metric calculated for my campaigns?”. In this blog we will explain how search lost IS (rank) is calculated by Google and ways you can improve your Ad Rank.
What is Ad Rank?
To begin, we need to understand what Ad Rank is. Ad Rank is a score that determines your ad position relative to other ads. According to Google the rank is calculated using a combination of the following:
- Your bid
- Ad quality including relevance of ad to search terms, landing page experience, expected clickthrough rate
- Ad Rank thresholds, which is the minimum bid for your ads to show
- The context of the search query – this includes the search terms in the query, the user location, time, device, and other search results that appear on the search page
- Impact of ad extensions and ad format – including more useful information about your business such as sitelinks, phone number and location can help improve the impact of your ad
